Heat the olive oil in a frying pan, add the onions and cook over a gentle heat for about 5 minutes, until soft. Add the pumpkin or squash along with the sage and cook for a further 10 minutes, stirring occasionally, until it starts to soften and turn golden.

Stir in the vegetable stock, season with sea salt and freshly ground black pepper then bring to the boil. Simmer for 10 minutes, until the pumpkin or squash is very soft. Pour in the cream, bring back to the boil then purée with a hand-held blender.

In a separate, dry frying pan toast the pumpkin seeds until they are golden. Meanwhile, break half of the crispbreads into croutons.

Ladle the soup into 6 warm bowls, top each with a handful of croutons and a sprinkling of toasted pumpkin seeds. Serve straight away with a couple of Ryvita on the side.
